I booked on PRINCE2 classroom course and on the Wednesday before the start date advising the course was not running and offering a virtual class alternative. I declined and took a refund but I had taken a week off work and couldn't find an alternative with such short notice. It seems very fishy to me and I wouldn't book with them again.
We recently used ProjStudy remote training. I really struggled with the way the training was delivered. The trainer spoke with a very distinct accent and the grammar of his sentences were not straightforward English. There was a strong focus on learning a large number of sentences by wrote in order to pass the exam. I did pass, but came away having learned very little. I don't want to use them again. As far as I can tell ProjStudy are based outside the UK and the whole operation feels like an an overseas call centre, which is not a good way to spend two days training.
